The invention relates to apparatus for the ianufacture of paper board, more particul`The inventiomconsists in the means cmhereinafter described.

In the manufacture .of corrugated paper yfaced board and in/a'subsequent operation to apply the second facing strip to the opposite side -of the board. The single faced corrugated material is capable of being The arrangement is preferably such that the corrugations.

E is a reel of plain paper from which theA strips'fed over the guide rolls F and G into contact with the glued corrugated strip.

After the facing strip and corrugated strip are brought into contact, they are fed through the drying apparatus. This consists of a hot plate H on which the combined strip rests, together with means for pressing the strip in contact with the plate The plate ll formedof a hollow member superar-s omer N y 'Specification of Letters Patent.

.i temperature.

plied with steam, to maintain the proper Patented May'lg 1912.

The upper face-of .this plate entends 'in ,the'plane of the feed and for sufficient length to insure the proper 'drying of the material. For holding the 'material in bontact with the' hot plate,'I preferably? einploy. a series of transversely extendingindependent presser bars I. These are preferably in the form of rollers which are 'free to rotatebut arelimited' as to longitudinal movement by pinsvor stops J The latter may be secured to the plate and projectupward into the path of the end portions J of the rollers, which are preferably 'slightly reduced in diameter so as to reduce the'friction upon the pin or stopJ.. g

. K are strips extending longitudinally of .the plate at the ends of the rollers and forming guides therefor. s

With the apparatus as thus fardescribed it is evident that the material as itis fed from the plate H, will be held in close contact therewith while'the individual rollers or presser bars' Lwill maintain all portions in' equally good contact. If the hot plate is of sufficient' length the material maybe dried without further apparatus, but where it is desired to accelerate the action or reduce the length of theplate, a Idrying hood may be employed. As shown L is a hood consisting of anl uppenplate L covered with suitable' heat insulating material suchv as M.

N are 'curtains depending from the plate L at lthe sidesthereof, extending down to the bed H.

'O are heating steam coils arranged beneath the hood above the rolls l. At the forward end ofthe hood' the conduit P is attached, which preferably leads to an exhaust fan (not shown) by which the air and moisture in the hood is constantly removed.

With the construction just described, the yheat of the plate H as well as that radiatingfrom' the coils O, will expel the moisture from the paper board.y The moist air will beremoved through the conduit P. There is however, a greater amount of moisture in the hood at the forward end thereof, than at the rear end, due to the fact that the air in exhausting is drawn forward. This is desirable as it prevents the mere surface drying of the paper by maintaining it for a `time in a comparatively moist atmosphere, but as the material is fed toward the rear, the amount of moisture in the atmosphere is progressivelydecreased so as to complete .l5 f v'dried thereover, and a series of'transverselythereover, a4 plurality ofpresser bars foryieldably 1o 1 pressure placed upon the .material by one presser bar being. independent of the re-l the drying. 'The feed., of fhe materia -through the apparatus may be effected by suitable .feed rollers Q at the rear end' thereof.

'v What I `claim asmy invention is:

' T1. The icombinatior'i with a hot plate, of. means for. feeding the .material to be dried holding the .material incontact with sald plate' during -its movement, the
